You can assign users to a group. To do so:
- Go to Partner Center > Businesses > Multi-Location Groups > Group Name > Users.
- Click Add Users.
- Find the user you wish to add.
- If you wish to add the user to the entire group, select Entire group. Alternatively, if you wish to only allow users to access specific sub-groups, click Select sub-groups.
- If you've chosen Select sub-groups, you will be able to sort through the various sub-groups and add the user to individual sub-groups. This can be done by clicking + next to the sub-groups you wish the user to have access to.
